The Python editor is based upon the Ace editor and includes syntax highlighting, code folding and (semi) intelligent auto The first line (from microbit import *) tells MicroPython to get all the bits of Python needed to program the micro:bit. La version utilisée sur le BBC micro :bit est appelée MicroPython. You can connect wired headphones or a speaker to pin 0 and GND on the edge connector to hear the sounds. MicroPython is able to recognise the following gestures: up, down , left, right, face up, face down, freefall, 3g, 6g , 8g, shake. If you haven’t learned the basic tutorial ( Makecode version of Tutorial), we strongly recommend you to learn it first. Note. While most of the names should be obvious, the 3g, 6g and 8g gestures apply when the device encounters these levels of g-force (like when an astronaut is launched into space). It is often around 20mA and providing any more than this will likely burn out the LED. They’re called Image. Links to the documentation, reference and projects.
